Pasque-Flower. 



Calyx of 6 petaloid membranaceous sepals, imbricated in 

 aestivation in two series, silky-bairy externally, at length 

 deciduous. Petals, or rather sterile stamens, gland-like, 

 sessile or unguiculate, very small, shorter than the fertile 

 stamens, or none. Stamens indefinite, in several series, 

 hypogynous : filaments filiform, glabrous: anthers short, 

 fixed by the base, neither extrorse nor introrse ; the cells 

 opening lengthwise laterally. Pistils numerous, capitate 

 on the globular or hemispherical receptacle : ovary one- 

 celled, one-ovuled, prolonged from the apex into a hairy 

 style many times exceeding the ovary ; the stigma unilat- 

 eral at its naked summit. Ovule suspended, anatropous ; 

 the raphe dorsal. 



Fruit a head of many sessile achenia, which are caudate 

 Avith the elongated and persistent plumose-bearded styles : 

 receptacle (gynophore) hemispherical. Seed suspended 

 from the summit of the cell, oblong. Albumen between 

 corneous and fleshy. Embryo minute, next the hilum, cor- 

 date, the short cotyledons spreading : radicle superior. 



Herbs, with fusiform or thickened and ligneous perennial 

 roots bearing abbreviated caudexes at their summit ; whence 

 is emitted, from a kind of scaly bud, a vernal, simple, one- 

 flowered, involucrate scape, and soon afterwards, or at the
